I tracked it > down to fs/block_dev.c do_open() which returns -ENOXIO for /dev/ubd1. Please check (the age of filesystem seems the culprit, maybe I've experienced this exact problem on that FS) that the minor for /dev/ubd1 is 16, and in case recreate the device node (ubd2 would be 32 and so on). Long time ago there was no partition support in UML so ubd1 had minor 1, but that has changed. > I also tried creating the filesystem in host kernel but then I am > unable to mount it. My hypotesis would explain this too. -- Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
